What exactly do you mean? (1) PIL creates a list which can be easily converted by numpy to a numpy.array or (2) with the help of numpy one can create a numpy.array from an image directly? Since I will have to pass the list or numy.array to C anyway I don't see any advantage to (1) although (2) can be useful.
